SKU CH-B0YD-XDM87

An 180 W ATX unit with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for quiet, low-power systems

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower energy use and heat via 80 PLUS Gold efficiency
  • Near-silent at low loads thanks to Zero RPM fan mode
  • Clean, stable power from resonant LLC and DC-to-DC design
  • Reduced coil whine for quieter operation under load

Compact 1U ATX supply for space-constrained builds

This KHACHIMO ACE-818APM-RS delivers 180 W of continuous power in a 1U form factor suited to small-chassis desktops and thin rack enclosures. It targets system integrators and hobbyists who need an ATX-compatible unit that fits where standard PSUs cannot.

Gold efficiency with semi-passive cooling

80 PLUS Gold certification keeps energy waste low and component temperatures down during typical workloads. A Zero RPM fan mode stops the fan entirely at low and medium loads, while resonant LLC topology with DC-to-DC conversion reduces coil whine and supports deeper sleep states.

Modern Standby support for instant wake

Modern Standby compatibility allows the system to resume from sleep almost instantly while maintaining network connectivity. The bundled topology and conversion design work together to sustain this low-power state without audible noise or voltage instability.

Highlights

  • Faster wake from sleep with Modern Standby support
  • Lower energy use and heat via 80 PLUS Gold efficiency
  • Near-silent at low loads thanks to Zero RPM fan mode
  • Clean, stable power from resonant LLC and DC-to-DC design
  • Reduced coil whine for quieter operation under load

Questions about this item

How do I install this 1U ATX power supply and which step do builders often miss?

Mount the unit in a 1U bay using its four screw holes, connect the 24-pin ATX and CPU power cables, then verify the rear voltage selector matches your mains supply — many forget that last check.

What maintenance will this 180W Gold-rated unit need over its life?

Clean dust from the intake grill every six to twelve months; the Zero RPM fan mode reduces bearing wear, so fan replacement is rarely required during normal service.

Which limit appears first when this supply runs at sustained load?

The 180W continuous output ceiling is reached before thermal or efficiency limits, so total system draw must stay below that figure.
